Formatting date/time of a label-item (within a list-card-widget in a page) with YAML

nfortenatly does not work:


this widget “oh-label-item” is part of a list card. Also the selection of a special list type like Media List has no impact.

What i am a bit wondering is that already on the item level, where i have added the metadata and pattern the time is shown in the original format and not with the format adden in the pattern
